HINT:

• Use the same procedure for the RH side and LH side.
• The following procedure is for the LH side.

CAUTION:

• Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
• If the airbag deploys for any reason, it may cause a serious accident.

NOTICE:

• If the front airbag sensor has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
• When installing the front airbag sensor, make sure that the SRS wiring does not interfere with or is not pinched between other parts.
• Make sure that the front airbag sensor pin (claw) is securely inserted into the body hole.
• Tighten the bolt while holding the front airbag sensor because the front airbag sensor pin (claw) is easily damaged.
